Macintosh Platform You can use the standard Macintosh fonts to type the necessary characters in Spanish. Press the key combination option-e (press and hold the option key, and then press the "e" key). Release both and press the vowel that you want accented

Note: According to the powers that be at the RAE (Real Academia Española) it is still obligatory to use accents with capital letters. However, it is very common to see un accentuated capital letters such as Á Ú Í Ó and in certain places such as neon signs etc. it is difficult to actually do.
